BUG H2O Table To Frame

Dear all,
there is a bug in Knime (v 3.5.3 and v 3.6 are both affected). When I try to convert a table in H2O frame some columns are not present in H2O Table To Frame node.
The problem is serious and make h2o not usable.
Please find attached a sample workflow with the problem. Do you have any idea on how to solve it?
Thanks in advance

Dear all,

I experienced the same issue above described and this is causing serious and severe delays on my work.
I would appreciate if you could propose a solution ad soon as possible.

Thanks and kind regards

Here’s a workaround for your test case. Since the input table contains a string, the Table to H2O node needs a valid domain. So you can insert a Domain Calculator node (making sure to uncheck the Restrict number of possible values checkbox in the configuration) and it will work.

Sorry for the inconvenience. I’ll investigate further - thanks for the feedback!


Many thanks! It works very well!
